‘A single optical fiber’: Scientists build a silicon-less computer that uses light waves and surpasses existing systems for classification โ€“ could this be the ultimate AI CPU?

In an era when the environmental footprint of large-scale AI systems is under increasing scrutiny, a team of international scientists has developed a potentially groundbreaking new solution.

The team, led by Prof. Mario Chemnitz and Dr. Bennet Fischer from the Leibniz Institute for Photonic Technology (Leibniz IPHT) in Jena, has built a computer that uses light waves instead of silicon, all through a single optical fiber .
